FIELD OF THE INVENTION

The present invention relates to novel heteroleptic iridium carbene complexes. In particular, these iridium complexes are phosphorescent and are useful as emitters in OLED devices.

BACKGROUND

Opto-electronic devices that make use of organic materials are becoming increasingly desirable for a number of reasons. Many of the materials used to make such devices are relatively inexpensive, so organic opto-electronic devices have the potential for cost advantages over inorganic devices. In addition, the inherent properties of organic materials, such as their flexibility, may make them well suited for particular applications such as fabrication on a flexible substrate. Examples of organic opto-electronic devices include organic light emitting devices (OLEDs), organic phototransistors, organic photovoltaic cells, and organic photodetectors. For OLEDs, the organic materials may have performance advantages over conventional materials. For example, the wavelength at which an organic emissive layer emits light may generally be readily tuned with appropriate dopants.

OLEDs make use of thin organic films that emit light when voltage is applied across the device. OLEDs are becoming an increasingly interesting technology for use in applications such as flat panel displays, illumination, and backlighting. Several OLED materials and configurations are described in U.S. Pat. Nos. 5,844,363, 6,303,238, and 5,707,745, which are incorporated herein by reference in their entirety.

One application for phosphorescent emissive molecules is a full color display. Industry standards for such a display call for pixels adapted to emit particular colors, referred to as “saturated” colors. In particular, these standards call for saturated red, green, and blue pixels. Color may be measured using CIE coordinates, which are well known to the art.

One example of a green emissive molecule is tris(2-phenylpyridine) iridium, denoted Ir(ppy)₃, which has the following structure:

In this, and later figures herein, we depict the dative bond from nitrogen to metal (here, Ir) as a straight line.

As used herein, the term “organic” includes polymeric materials as well as small molecule organic materials that may be used to fabricate organic opto-electronic devices. “Small molecule” refers to any organic material that is not a polymer, and “small molecules” may actually be quite large. Small molecules may include repeat units in some circumstances. For example, using a long chain alkyl group as a substituent does not remove a molecule from the “small molecule” class. Small molecules may also be incorporated into polymers, for example as a pendent group on a polymer backbone or as a part of the backbone. Small molecules may also serve as the core moiety of a dendrimer, which consists of a series of chemical shells built on the core moiety. The core moiety of a dendrimer may be a fluorescent or phosphorescent small molecule emitter. A dendrimer may be a “small molecule,” and it is believed that all dendrimers currently used in the field of OLEDs are small molecules.

As used herein, “top” means furthest away from the substrate, while “bottom” means closest to the substrate. Where a first layer is described as “disposed over” a second layer, the first layer is disposed further away from substrate. There may be other layers between the first and second layer, unless it is specified that the first layer is “in contact with” the second layer. For example, a cathode may be described as “disposed over” an anode, even though there are various organic layers in between.

As used herein, “solution processable” means capable of being dissolved, dispersed, or transported in and/or deposited from a liquid medium, either in solution or suspension form.

A ligand may be referred to as “photoactive” when it is believed that the ligand directly contributes to the photoactive properties of an emissive material. A ligand may be referred to as “ancillary” when it is believed that the ligand does not contribute to the photoactive properties of an emissive material, although an ancillary ligand may alter the properties of a photoactive ligand.

As used herein, and as would be generally understood by one skilled in the art, a first “Highest Occupied Molecular Orbital” (HOMO) or “Lowest Unoccupied Molecular Orbital” (LUMO) energy level is “greater than” or “higher than” a second HOMO or LUMO energy level if the first energy level is closer to the vacuum energy level. Since ionization potentials (IP) are measured as a negative energy relative to a vacuum level, a higher HOMO energy level corresponds to an IP having a smaller absolute value (an IP that is less negative). Similarly, a higher LUMO energy level corresponds to an electron affinity (EA) having a smaller absolute value (an EA that is less negative). On a conventional energy level diagram, with the vacuum level at the top, the LUMO energy level of a material is higher than the HOMO energy level of the same material. A “higher” HOMO or LUMO energy level appears closer to the top of such a diagram than a “lower” HOMO or LUMO energy level.

As used herein, and as would be generally understood by one skilled in the art, a first work function is “greater than” or “higher than” a second work function if the first work function has a higher absolute value. Because work functions are generally measured as negative numbers relative to vacuum level, this means that a “higher” work function is more negative. On a conventional energy level diagram, with the vacuum level at the top, a “higher” work function is illustrated as further away from the vacuum level in the downward direction. Thus, the definitions of HOMO and LUMO energy levels follow a different convention than work functions.

More details on OLEDs, and the definitions described above, can be found in U.S. Pat. No. 7,279,704, which is incorporated herein by reference in its entirety.

DETAILED DESCRIPTION

Generally, an OLED comprises at least one organic layer disposed between and electrically connected to an anode and a cathode. When a current is applied, the anode injects holes and the cathode injects electrons into the organic layer(s). The injected holes and electrons each migrate toward the oppositely charged electrode. When an electron and hole localize on the same molecule, an “exciton,” which is a localized electron-hole pair having an excited energy state, is formed. Light is emitted when the exciton relaxes via a photoemissive mechanism. In some cases, the exciton may be localized on an excimer or an exciplex. Non-radiative mechanisms, such as thermal relaxation, may also occur, but are generally considered undesirable.

The initial OLEDs used emissive molecules that emitted light from their singlet states (“fluorescence”) as disclosed, for example, in U.S. Pat. No. 4,769,292, which is incorporated by reference in its entirety. Fluorescent emission generally occurs in a time frame of less than 10 nanoseconds.

More recently, OLEDs having emissive materials that emit light from triplet states (“phosphorescence”) have been demonstrated. Baldo et al., “Highly Efficient Phosphorescent Emission from Organic Electroluminescent Devices,” Nature, vol. 395, 151-154, 1998; (“Baldo-I”) and Baldo et al., “Very high-efficiency green organic light-emitting devices based on electrophosphorescence,” Appl. Phys. Lett., vol. 75, No. 3, 4-6 (1999) (“Baldo-II”), which are incorporated by reference in their entireties. Phosphorescence is described in more detail in U.S. Pat. No. 7,279,704 at cols. 5-6, which are incorporated by reference.

FIG. 1 shows an organic light emitting device 100. The figures are not necessarily drawn to scale. Device 100 may include a substrate 110, an anode 115, a hole injection layer 120, a hole transport layer 125, an electron blocking layer 130, an emissive layer 135, a hole blocking layer 140, an electron transport layer 145, an electron injection layer 150, a protective layer 155, a cathode 160, and a barrier layer 170. Cathode 160 is a compound cathode having a first conductive layer 162 and a second conductive layer 164. Device 100 may be fabricated by depositing the layers described, in order. The properties and functions of these various layers, as well as example materials, are described in more detail in U.S. Pat. No. 7,279,704 at cols. 6-10, which are incorporated by reference.

More examples for each of these layers are available. For example, a flexible and transparent substrate-anode combination is disclosed in U.S. Pat. No. 5,844,363, which is incorporated by reference in its entirety. An example of a p-doped hole transport layer is m-MTDATA doped with F.sub.4-TCNQ at a molar ratio of 50:1, as disclosed in U.S. Patent Application Publication No. 2003/0230980, which is incorporated by reference in its entirety. Examples of emissive and host materials are disclosed in U.S. Pat. No. 6,303,238 to Thompson et al., which is incorporated by reference in its entirety.

FIG. 2 shows an inverted OLED 200. The device includes a substrate 210, a cathode 215, an emissive layer 220, a hole transport layer 225, and an anode 230. Device 200 may be fabricated by depositing the layers described, in order. Because the most common OLED configuration has a cathode disposed over the anode, and device 200 has cathode 215 disposed under anode 230, device 200 may be referred to as an “inverted” OLED. Materials similar to those described with respect to device 100 may be used in the corresponding layers of device 200. FIG. 2 provides one example of how some layers may be omitted from the structure of device 100.

The simple layered structure illustrated in FIGS. 1 and 2 is provided by way of non-limiting example, and it is understood that embodiments of the invention may be used in connection with a wide variety of other structures. The specific materials and structures described are exemplary in nature, and other materials and structures may be used. Functional OLEDs may be achieved by combining the various layers described in different ways, or layers may be omitted entirely, based on design, performance, and cost factors. Other layers not specifically described may also be included. Materials other than those specifically described may be used. Although many of the examples provided herein describe various layers as comprising a single material, it is understood that combinations of materials, such as a mixture of host and dopant, or more generally a mixture, may be used. Also, the layers may have various sublayers. The names given to the various layers herein are not intended to be strictly limiting. For example, in device 200, hole transport layer 225 transports holes and injects holes into emissive layer 220, and may be described as a hole transport layer or a hole injection layer. In one embodiment, an OLED may be described as having an “organic layer” disposed between a cathode and an anode. This organic layer may comprise a single layer, or may further comprise multiple layers of different organic materials as described, for example, with respect to FIGS. 1 and 2.

Structures and materials not specifically described may also be used, such as OLEDs comprised of polymeric materials (PLEDs) such as disclosed in U.S. Pat. No. 5,247,190 to Friend et al., which is incorporated by reference in its entirety. By way of further example, OLEDs having a single organic layer may be used. OLEDs may be stacked, for example as described in U.S. Pat. No. 5,707,745 to Forrest et al, which is incorporated by reference in its entirety. The OLED structure may deviate from the simple layered structure illustrated in FIGS. 1 and 2. For example, the substrate may include an angled reflective surface to improve out-coupling, such as a mesa structure as described in U.S. Pat. No. 6,091,195 to Forrest et al., and/or a pit structure as described in U.S. Pat. No. 5,834,893 to Bulovic et al., which are incorporated by reference in their entireties.

Unless otherwise specified, any of the layers of the various embodiments may be deposited by any suitable method. For the organic layers, preferred methods include thermal evaporation, ink-jet, such as described in U.S. Pat. Nos. 6,013,982 and 6,087,196, which are incorporated by reference in their entireties, organic vapor phase deposition (OVPD), such as described in U.S. Pat. No. 6,337,102 to Forrest et al., which is incorporated by reference in its entirety, and deposition by organic vapor jet printing (OVJP), such as described in U.S. patent application Ser. No. 10/233,470, which is incorporated by reference in its entirety. Other suitable deposition methods include spin coating and other solution based processes. Solution based processes are preferably carried out in nitrogen or an inert atmosphere. For the other layers, preferred methods include thermal evaporation. Preferred patterning methods include deposition through a mask, cold welding such as described in U.S. Pat. Nos. 6,294,398 and 6,468,819, which are incorporated by reference in their entireties, and patterning associated with some of the deposition methods such as ink-jet and OVJD. Other methods may also be used. The materials to be deposited may be modified to make them compatible with a particular deposition method. For example, substituents such as alkyl and aryl groups, branched or unbranched, and preferably containing at least 3 carbons, may be used in small molecules to enhance their ability to undergo solution processing. Substituents having 20 carbons or more may be used, and 3-20 carbons is a preferred range. Materials with asymmetric structures may have better solution processability than those having symmetric structures, because asymmetric materials may have a lower tendency to recrystallize. Dendrimer substituents may be used to enhance the ability of small molecules to undergo solution processing.

Devices fabricated in accordance with embodiments of the present invention may further optionally comprise a barrier layer. One purpose of the barrier layer is to protect the electrodes and organic layers from damaging exposure to harmful species in the environment including moisture, vapor and/or gases, etc. The barrier layer may be deposited over, under or next to a substrate, an electrode, or over any other parts of a device including an edge. The barrier layer may comprise a single layer, or multiple layers. The barrier layer may be formed by various known chemical vapor deposition techniques and may include compositions having a single phase as well as compositions having multiple phases. Any suitable material or combination of materials may be used for the barrier layer. The barrier layer may incorporate an inorganic or an organic compound or both. The preferred barrier layer comprises a mixture of a polymeric material and a non-polymeric material as described in U.S. Pat. No. 7,968,146, PCT Pat. Application Nos. PCT/US2007/023098 and PCT/US2009/042829, which are herein incorporated by reference in their entireties. To be considered a “mixture”, the aforesaid polymeric and non-polymeric materials comprising the barrier layer should be deposited under the same reaction conditions and/or at the same time. The weight ratio of polymeric to non-polymeric material may be in the range of 95:5 to 5:95. The polymeric material and the non-polymeric material may be created from the same precursor material. In one example, the mixture of a polymeric material and a non-polymeric material consists essentially of polymeric silicon and inorganic silicon.

Devices fabricated in accordance with embodiments of the invention may be incorporated into a wide variety of consumer products, including flat panel displays, computer monitors, medical monitors, televisions, billboards, lights for interior or exterior illumination and/or signaling, heads up displays, fully transparent displays, flexible displays, laser printers, telephones, cell phones, personal digital assistants (PDAs), laptop computers, digital cameras, camcorders, viewfinders, micro-displays, vehicles, a large area wall, theater or stadium screen, or a sign. Various control mechanisms may be used to control devices fabricated in accordance with the present invention, including passive matrix and active matrix. Many of the devices are intended for use in a temperature range comfortable to humans, such as 18 degrees C. to 30 degrees C., and more preferably at room temperature (20-25 degrees C.).

The materials and structures described herein may have applications in devices other than OLEDs. For example, other optoelectronic devices such as organic solar cells and organic photodetectors may employ the materials and structures. More generally, organic devices, such as organic transistors, may employ the materials and structures.

The terms halo, halogen, alkyl, cycloalkyl, alkenyl, alkynyl, arylkyl, heterocyclic group, aryl, aromatic group, and heteroaryl are known to the art, and are defined in U.S. Pat. No. 7,279,704 at cols. 31-32, which are incorporated herein by reference.

Many known metal carbene complexes have poor OLED device performance. There are many possible factors can contribute to this poor performance, such as high sublimation temperature of the emitter, long triplet transient lifetime of the emitter, low triplet of the host, unbalanced charges in the device, etc. In the presently disclosed compounds, two different carbene ligands are used to tune the color and photophysical properties in deep blue emitters, making the compounds heteroleptic. Through this approach, different physical properties can be tuned by different set of ligands within a single molecule.

DFT calculations were used to predict the properties of disclosed compounds and comparative compounds. The HOMO, LUMO, the HOMO-LUMO energy gap and triplet energies for each structure were calculated using DFT calculations with the Gaussian software package at the B3LYP/cep-31 g functional and basis set. The DFT calculations are summarized in Table 1. Ex. is an abbreviation for Example, Compd. is an abbreviation for Compound, CC is an abbreviation for Comparative Compound.

Table 1 shows HOMO, LUMO energy levels, the HOMO-LUMO energy gap and triplet energies for a series of dibenzofuran (DBF) containing heteroleptic carbene complexes, in comparison to homoleptic tris complexes, i.e., CC1 to CC4. It can be seen in this table from Ex.1 to 9 that when one or two DBF containing carbene ligands in a tris complex is replaced by another carbene complex, for example,

its HOMO energy is raised up in each case while maintaining its Ti energy. The biggest difference of 0.52 eV can be seen in Ex.5 vs. Ex.6. The HOMO of heteroleptic complex 4002 is −5.04 eV, while its tris CC3 is −5.56 eV. Without being bound by theory, it is believed that a higher HOMO energy of an emitter will facilitate the emitter to trap the hole, which can result in better device efficiency and lifetime.

Ex. 10 to 13 are for DBF containing heteroleptic carbene complex with one or two carbene ligands having fused pyridine on imidazole ring. It has been unexpectedly shown that the singlet gaps of these compounds (−3.59 to −3.72 eV) are much narrower than that of tris compound (−4.18 eV for CC4), and their Ti energies (448, 449 nm) actually become higher than that of tris compound (451 nm). This is opposite to the usual case that the change of singlet gap of a compound will shift at the same direction as the change of its triplet energy. Without being bound by theory, with a certain triplet emission energy, the emitter having a smaller singlet energy is highly desired. Lowering the singlet energy is expected to reduce the likelihood of singlet excited state decomposition, thereby resulting in improved device lifetimes.

Physical Characterization

Photo physical characterization has been done with inventive complex 4003 vs. comparative complex CC1. PMMA and Ir complex (5 wt %) are weighed out and dissolved in toluene. The solution is filtered through a 2 micron filter and drop cast onto a precleaned quartz substrate. PL quantum efficiency (Φ_(T)) measurements were carried out on a Hamamatsu C9920 system equipped with a xenon lamp, integrating sphere and a model C10027 photonic multi-channel analyzer. PL transient lifetime (TT) measurements were carried out by time correlated single photon counting method using a Horiba Jobin Yvon Fluorolog-3 integrated with an IBH datastation hub using a 335 nm nanoLED as the excitation source. All measurement was conducted at room temperature, and the results are summarized in Table 2.

TABLE 2 Physical Characterization Ex. Compd. No. Structure T1 (nm) Φ_(T) (%) τ_(T) (μs) 21 4003

450 87 15 22 CC1

442 71 28 Based on the photo physical characterization, it is unexpectedly observed that the heteroleptic carbene complex 4003 has much higher PL quantum efficiency, and smaller PL transient lifetime. Without being bound by theory, a smaller transient lifetime will reduce the chance of decomposition and excited state quenching of triplet exciton of the emitter, which will in turn enhance device performance. A higher PL quantum efficiency value of an emitter is desired for a high efficiency device performance.

EXPERIMENTAL Experimental Procedures

Chemical abbreviations used throughout this document are as follows: dba is dibenzylideneacetone, EtOAc is ethyl acetate, PPh₃ is triphenylphosphine, dppf is 1,1′-bis(diphenylphosphino)ferrocene, DCM is dichloromethane, SPhos is dicyclohexyl(2′,6′-dimethoxy-[1,1′-biphenyl]-3-yl)phosphine, THF is tetrahydrofuran.

A process for preparing the claimed iridium heteroleptic complexes is exemplified below:

A 250 mL flask was charged with 4-iododibenzo[b,d]furan (2.8 g, 9.52 mmol), 4-methyl 1H-imidazole (1.56 g, 19.04 mmol), CuI (0.182 g, 0.95 mmol), Cs₂CO₃ (6.51 g, 20 mmol), cyclohexane-1,2-diamine (0.435 g, 3.81 mmol) and DMF (100 mL). The reaction mixture was bubbled with N₂ for 30 minutes and then heated up to 150° C. for 20 hours. The mixture was cooled down and added into water/ethyl acetate. The organic phase was washed with brine and run through a silica gel plug with ethyl acetate. After removal of solvent, the organic residue was recrystallized from ethyl acetate/hexane to get about 1.8 g (76% yield) white solid for next step.

1-Dibenzo[b,d]furan-4-yl)-4-methyl-1H-imidazole (1.2 g, 4.83 mmol) was dissolved in ethyl acetate (40 mL) in a 250 mL flask. To the mixture, MeI (3.43 g, 24.17 mmol) was added. The reaction mixture was stirred for 24 hours at room temperature. After filtration, 1.8 g (95% yield) of white salt was obtained.

A 100 mL round bottom flask was charged with 3-methyl-1-phenyl-1H-imidazol-3-ium iodide (16.98 g, 59.3 mmol), silver oxide (6.88 g, 29.7 mmol) and acetonitrile (180 mL) to give a tan suspension. The reaction mixture was stirred at room temperature overnight. Solvent was removed by vacuum distillation and the residue was used for next step without purification.

A 100 mL round-bottomed flask was charged with iodide salt (309 mg, 0.794 mmol), silver oxide (92 mg, 0.397 mmol), and acetonitrile (100 mL) to give a tan suspension. Reaction mixture was stirred in room temperature for overnight. Solvent was removed by vacuum distillation and residue was used for next step without purification.

A 100 mL round-bottomed flask was charged with carbene dimer (287 mg, 0.265 mmol, prepared as described in US20050258742) and silver carbene complexes (395 mg, 0.795 mmol) in o-xylene (50 mL) to give a tan suspension. US20050258742 is herein incorporated in its entirety. The solution was heated to reflux for 3.5 hours. The solution was evaporated to dryness and the residue was subjected to column chromatography (SiO₂, pretreated with 20% Et₃N in hexanes, 50% EtOAc in hexanes) to yield the desired compound (46 mg, 11% yield, m/z (ESP+)=769)
